In addition to either 40 or 80 GBytes of memory for storing and viewing digital photos and video in a 5.3 × 3.1 × 1.1-inch package, this photo album also plays MP3 tunes. The unit’s 3.6-inch LCD display allows viewing image files in JPEG, TIFF, GIF, BMP and RAW formats or video in MPEG-1, MPEG-4, WMV9 and MJPEG formats. For picture-perfect viewing, the display requires backlighting and the built-in speaker requires audio amplification. In addition to these analog functions, several dc-to-dc converters or low drop out regulators provide the various supply voltages for other features such as reading external memory cards, the FM tuner or voice recorder.
